Ferret talk - Sep 2006 - Excluding a term on a search

Hi there,

I have a model with indexed fields (F1, F2, F3...).

I have a field-based search (+F1:..., +F2:...), and a global search 
(which queries all fields with the given terms). Both of them works ok, 
but I would like to exclude a term from the global search (though it 
should remain indexed to support the field-based search), is it 
possible?

Thanks in advance.

Of course, the thread topic should be ''Excluding a FIELD on a
search''.
I''m sorry...

Hi Raul,

You probably want to do something like this;

    require ''rubygems''
    require ''ferret''

    i = Ferret::I.new(:default_field => [:f1, :f2, :f3])

    i << {:f1 => "hello"}
    i << {:f2 => "hello"}
    i << {:f3 => "hello"}
    i << {:f4 => "hello"}

    puts "global"
    i.search_each("hello") {|d, s| puts "#{d}"}

    puts "field"
    i.search_each("f4:hello") {|d, s| puts "#{d}"}

This should print this out;

    global
    0
    1
    2
    field
    3

This should be pretty simple to do through acts_as_ferret too.

Cheers,
Dave
